A large study of US adults 65 and older enrolled in Medicare finds that the risk of Guillain-Barre syndrome (GBS)—a rare autoimmune disorder in which the body's immune system attacks its own nerves—doubles in adults 65 and older infected with respiratory syncytial virus (RSV). The study, published today in Clinical Infectious Diseases, involved 452,471 patients with RSV infection requiring medical care from 2011 through 2024. (Wappes, 11/14)

The new drug, developed by the not-for-profit TB Alliance, doesn’t just show promise to cut treatment times. The data indicate it has a better safety profile and the potential to defeat many strains that have become resistant to other antibiotics.
